I was agreeing that knowledge can help, but I was stating that incorrect
knowledge can hinder.  It is 'bad'.

Actually, it was an arithmetic question.  Nothing more than simple addition
and subtraction.

It didn't even have fractions.  Definitely of the elementary school level.

Oh, you use it now?  It's about time.  Regardless, science isn't actually
dependent on metric.  The units of measure are quite arbitrary.

Do they get marks for work with no correct answer?  I was under the
impression they did not.
